Mammographic Imaging Process in Medical Imaging

To spread out the breast tissue and reduce its thickness, ensuring a more uniform image quality

Breast tomosynthesis provides three-dimensional images of the breast, allowing for better visualization and improved detection of abnormalities.

Conventional screen-film mammography uses film to capture the images, while digital mammography uses electronic detectors to capture and store the images.

<p>Breast tissues lack subject contrast because they have similar effective atomic numbers and density, making it difficult to differentiate between them on a radiograph.</p> Signup and view all the answers

<p>In conventional radiography, subject contrast is great due to the large difference in mass density and atomic number among bone, muscle, fat, and lung tissue, whereas breast imaging faces the challenge of low subject contrast due to the similarity in effective atomic numbers and density of breast tissues.</p> Signup and view all the answers
